How to get the status of monitored objects and generate alarms using SNMP

 

Product

DX NetOps Spectrum

 

 

Quetion

We have monitoring targets that monitor the I/F status with ifAdminStatus and ifOperStatus using SNMP, and also obtain CPU usage and memory usage with SNMP Get.

Currently, monitoring is done with a different product in the end user's environment, but we are considering monitoring the above targets with Spectrum.

Please tell me how to detect state transitions of monitored targets using SNMP and generate alarms.

 

 

Q1: Interface status

On the Spectrum OneClick screen, select a registered host in the topology and refer to the "Interface" tab at the bottom of the screen to check the interface status of the target host. 

I have confirmed that if an interface on the target host goes down, the change is reflected after a short delay.

However, it seems that no alarms are being generated.

I think the event definition and alarm settings are insufficient. 

Please let me confirm how to set it up.

 

 

Q2: Resource monitoring

When I select a registered host in the OneClick topology and open the “Information” tab, I see a setting called “Thresholds and Watch” where I can set CPU or memory thresholds to generate an alarm when the utilization exceeds the thresholds I have set.

Is this correct?

 

Thanks,

OOTB spectrum creates interface alarms based on RFC 1312 traps received from the devices. If the devices are not sending those traps, Spectrum can poll the status of ports and create alarms for those. It would not be recommended to have high number of polled interfaces, as this creates some load on the system. What you see in the interface, as status, is read by the system on the fly. You see the interface status, because you're seeing the interface list. Otherwise, that would not be displayed. 

This should help for the active polling of ports.

For resource monitoring check this.
